Accelerated power-on method based on solid state disk and solid state disk

The embodiment of the invention provides an accelerated power-on method based on a solid state disk, the solid state disk, computer equipment and a computer readable storage medium, and the method comprises the following steps: when detecting that the power supply voltage of the solid state disk is abnormal, downwards brushing a current first mapping table to a storage area of the solid state disk; when it is detected that the power supply voltage returns to normal, a first mapping table in a storage area of the solid state disk is read, and a temporary mapping table is recovered based on the first mapping table; and recovering the second mapping table when the voltage is abnormal according to the dirty page bitmap of the second mapping table before the voltage is abnormal and the temporary mapping table. According to the method and the device, the second mapping table can be directly recovered by reading the first mapping table in the storage area of the SSD under the condition that the voltage of the extern
